Dimming Operation 

• Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.
• Compatible with Leading edge or trailing edge triac dimmers, but trailing edge dimmers work better..
• Please try to use dimmers with power at least 1.5 times as the output power of the driver.
